Servicing an Old Sharp rp-117

Post by Olympusxander » 17 Jan 2018 04:08

Hello.

I am fairly new to owning records and I already have two different turntables. I have a Motorola SK14b which I am using to play records off of my Sharp rp-117. The Sharp rp-117 is not refurbished or repaired other than a new platter drive belt (which I am not sure is the correct one) and a new tray gear. The unit does start up, the display lights function, all buttons seem to do their jobs, and it does start to play a record. It plays for about 30 to 45 seconds before it cuts out. I think the electronics are sound but mechanically has problems. I have read the maintenance Manuel but I don't really know enough about electronic repair to try to attempt myself. Any advice on how to advance with repairs will be very appreciated.

Thanks for reading and have a good day.

Not a turntable for a beginner to repair, has too much complexity for beginners. A: It is a linear tracking servo arm (more complex than average) and B: Both sides play (even more complex electronics and mechanical systems to deal with) and many technicians who don't work on turntables like this cringe when one gets brought into to repair. And uncommon when new, and not like parts were easy to get, and service support not too common even new.

Thanks for the reply.

I understand the complexity of the unit and that it is difficult to repair. If anyone knows a specialty shop or person that does repairs please let me know. It is a very unique turntable that I would love to get working again.

I don't know of any USA Sharp turntable specialists. The conventional models are likely repairable by good technicians provided it does not need Sharp specific spare parts, which are unobtainable. The RP 117 was uncommon in these United States, and repair knowledge thin on the ground. Not many were sold. Best wishes on finding someone who knows this machine and service literature.

Hi Olympusxander,

Not sure if you ever solved your Sharp RP-117 issues last year.

I have repaired and own one myself, and from what you describe it sounds like the small belt for moving the two tone-arms back and forth is worn / stretched / slipping. My belt was stretched when I got it, and it did the same as yours - start playing for a few secs, then shutdown. You can probably get away with a good quality elastic band for the time being if you want to try it out first.

See this thread, Soundbug is a real expert, and he also tells you the CORRECT size for the two required belts (I started out buying the too-small one too.....:o)

Let me know if you would like any more Help, I may have a few more ideas...... :wink: Happy New Year!
